Abstract

The invention discloses a charging power supply test load and system, belonging to the technical field of power supply test loads, comprising an energy storage capacitor connected in parallel with the output end of the charging power supply, a resistive discharge circuit and an inductive discharge circuit connected in parallel with the energy storage capacitor. The combination of the resistive discharge circuit and the inductive discharge circuit of the present invention can simulate the process of discharging the energy storage capacitor to zero and then recharging, and then accurately simulate various load characteristics of the charging power supply, and realize the energy storage capacitor by controlling the working time of the resistive discharge circuit. Back pressure and residual pressure adjustment, so as to truly restore various working condition parameters of the charging power supply.

Description

Technical field [0001] The present invention relates to the field of power test load, and more particularly to a charging power supply test load and system. Background technique [0002] A pulse charging power source (hereinafter referred to as a charging power source) for pulse power system storage capacitance (hereinafter referred to as a charging power) is generally charged at a certain repetition frequency, and the charging power supply is first charged in a single working cycle, and then the energy is The capacitor will discharge the load in a short period of time, which will then enter the next work cycle. The load will release all of the energy of all capacitances in a short time. Since the load is generally inductive, some energy returns are partially energy return, and the energy recovery circuit is recovered through the energy recovery circuit to the energy storage capacitor, so the end of one cycle ends. After that, when the next cycle begins, the energy storage capaci...
